>>9505378IF's OP is mostly late-taxed by now since they don't reissue stuff. It's dated too but I guess IF's strength is that it has a lot of 5mm ports compatible with official Hasbro stuff.
If you don't care about geewun aesthetics, the one Legends *Scale* OP that everyone in this thread likes is TFC's ST Commander based off Don Figueroa's GI Joe crossover concept. It is technically Legends scaled, just a fuckhuge one.
